"Hard to believe you were ever pregnant!" Everyone's freaking out over Rebecca Judd's post-baby body.

Less than two weeks after giving birth to identical twin boys Tom and Darcy, mother-of-four Rebecca Judd is back in her skinny jeans.

Bravo Mumma Judd, bravo.

Having remained active throughout her high-profile pregnancy, the 33-year-old posted a photo of her denim feat to Instagram on Monday night and said of the maternity jeans, “I may just live in these forever – so comfy.”

The photo was posted ahead of the recently expanded family’s first portrait, which Judd also shared on Monday evening. (Spoiler: it’s adorable, perfect in every way and will make you seriously consider having four children.)

“We made it!” the television presenter and model wrote. “This photo exhausts me just looking at it.”

But within moments of posting her outfit pic, comments of disbelief from many of Judd’s 557,000 followers rolled in.

“Hard to believe you were ever pregnant!” one commenter wrote, while another asked, “Is this you today after babies???”

Others took a kinder approach, with one woman writing, “Wow you do look amazing bec [sic]… you must have a tight fitness schedule.”

Another commented, “Did u just give birth to twins??? Stunning as ever!!”

But as ever, Judd’s commitment to keeping it real shone through, with the new mum adding the hashtag #feedburpsleeprepeat to one of the images.
